Crossword Genius

After a delivery job (4)

Ross

I believe the answer is:

post

This clue is a triple definition!

'after' is the first definition.
(prefix meaning after, eg post-war)

'a delivery' is the second definition.
(I've seen this before)

'job' is the third definition.
(I know that post is a type of job)

(Other definitions for post that I've seen before include "Upright length of wood or metal a permanent military establishment" , "(Holiday) communication" , "Send via the mail" , "A column" , "Part of address" .)

I've seen this clue in The Telegraph.
